Parameter Estimates

Jun 15, 2021 to Oct 2, 2026

Model Insight

With persistence 0.995, volatility shocks have a half-life of 147 trading days (~0.6 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 2.93 degrees of freedom, capturing fatter tails than a normal distribution.
